Abstract

A communication system for transmission, on a communication medium, intermittently appearing language information in the first audio frequency signals, including the system: non-continuous communication signals generator for, when the desired language information appears inn the first audio frequency signal, generation of the first communication signal in the first communication medium and the first communication signal would, based on a predetermined code, encode the first communication number into communication data block; communicatiion signal receiver for receiving from the communication medium second communication signals; communication signal processor which, in response to the communication signal receiver, processes the received second communication signal, for generation of processing blocks of communication data; measurement determination device, in response to the communication signal processor, for determination of the correct measurement of the processing block indicating a plurality of communication information; and rise frequency generator, for generation of a second audio signal when the measurement being in a predetermined range, for generation from a plurlaity of communication information processed blocks, and when the measurement being outside a predetermined range, for generation of a stuffing noise signal.
